LADLE-CAR.

To all whom it may concern- Be it'known that I, ERWIN C. SHERMAN, ofYoungstown, Mahoning county, Ohio, have invented anew ment in Ladle-Carsof which the following is a full, clear, andexact description, reference being had to the accompanying drawings, forming part of thisspecification, in which igure-l is an end view of a ladle car em- 0 yingmy invention; Fig. 2 is a similar view, largely diagrammatic,illustrating the dumping movement of the ladle; and Fig. 3 is asectional plan view showing a modified construction.

My inventionhas relation to dumping or ladle cars of that type in whichthe ladle is emptied by pouring from a spout located at or near the topof the ladle. In cars of this character as ordinarily constructedheretofore, when the ladle is tipped in the frame of the car there isconsiderable drop to the spout while pouring; and in order to bring thefinal position of the spout in the properrelation to the receptaclepoured into, it has been necessary either to allow considerable fall tothe metal during the first part of the pouring, which has resulted ingreat loss due to the the metal, or to lift the ladle from the car bymeans of an overhead crane and place it in a tilting cradle so arrangedas to give a shorter-fall of the metal, or to provide a movable troughwhich moves with the spout on the ladle. These expedients causeconsiderable inconvenience and added expense in the handling of themetal.

The present invention is'designed to provide means whereby anoveltipping action of the ladle is obtained, resulting in a largedecrease in the drop of the spout during the pouring operation.

In the accompanying drawings, the numeral 2 designates any usual orsuitable truck of a ladle car, and 3 the frame of the car supported onthe truck.

4 is the ladle, and 5 indicates a receptacle, into which the contents ofthe ladle are to be poured. The ladle is provided at each end with asupporting projection 6, these projections normally resting upon thesupporting surfaces 7 on the end frames of the car. The ladle isprovided near its top and at opposite sides of its center with theprojecting trunnions 8, which rest in the open and useful Improvesplashing of Specification of Letters Patent.

bearings 9 formed in the upper ends of the upwardly projecting portions3* of the car end frames. In dumping, the ladle is tilted upon one orthe other of the trunnions 8,

v according to whether it is desired to pour to the right or to theleft, and as these trunnions are located high up on the car,

it will be apparent that the movement of the ladle spout 10 during thepouring op eration will be very largely reduced.

In Fig. 1 I have shown the trunnions 8 as being carried by separatecastings, which are secured to the ladle. In the modificatio'u shown inFig. 3, I have shown the supporting projections 6, which carry the usualladle trunnions 6"*, as having integral extensions 6 upon which thetrunnions '8 (corresponding to the trunnions 8) are formed. The twoextensions 6* are connected by tie rod 6 and a spacer or separator 6 isplaced upon the tie rod between said extensions. This constructionprovides a square supporting frame around the top of the ladle, whichtends to prevent the top of the ladle fro trunnions 8 centered ,so thatthey -are always alined with the open bearings.

Owing to the high center of movement of the ladle, it is tip during thepouring operation owing to the shifting to the center of gravity. Toovercome this tendency, I preferably provide the lower portion of theframe of the car with the supporting feet or projections 11, which areadapted to rest upon the supports 12 adjacent to the track 13 upon whichthe car travels. I also preferably provide,adjacent to the supports 12 asuitable hook 14, which will engage over the projection 11 at the sideof the car opposite to that at which the pouring takes place and whichserves to hold down the frame ofthe car and to prevent the car fromtipping. The hook, however, may be used without the supports, or thesupports without the hook,

or any other suitable means may be employed for preventing the car fromtlppmg during the pouring operation. The trunnions 8 are so located thattheir centers are in vertical lines which fall outside of the trackrails 13.
